Abstract
A method of manufacturing an irregular electrode includes forming a first electrode line by continuously coating a first electrode slurry on a metal sheet, forming at least one second electrode line formed with a dotted line shape including uncoated portions positioned in parallel to the first electrode line by intermittently coating a second electrode slurry on the metal sheet that does not overlap the first electrode line, and forming the irregular electrode by notching the metal sheet with an irregular shape including the second electrode line and the first electrode line except for the uncoated portions of the at least one second electrode line.
